The best Shopify upsell apps combine product page offers, cart add-ons, and post-purchase funnels to lift AOV by 20–30%. That's not a rounding error — on a store doing $50,000/month, that's $10,000–$15,000 in additional revenue without a single extra ad dollar. And upselling to an existing customer is 68% cheaper than acquiring a new one.
The problem is choosing the right app. The Shopify App Store has dozens of upsell apps, and they all claim to "boost AOV." Some specialize in post-purchase offers. Others focus on bundles. A few try to do everything. This guide breaks down the seven best Shopify upsell apps for 2026, with verified ratings, real pricing, and honest pros and cons — so you can pick the one that fits your store, not the one with the best marketing page.
How Do the Best Shopify Upsell Apps Increase AOV?
Before comparing apps, it helps to understand where upsells work in the buying flow. There are four key touchpoints, and each converts differently:
- Product page upsells (frequently bought together, add-ons): 8–15% acceptance rate
- Cart drawer upsells (add items before checkout): 5–12% acceptance rate
- Checkout upsells (order bumps at payment): varies by app and plan
- Post-purchase upsells (one-click offers after payment): 3–8% acceptance rate
The best-performing stores don't pick one touchpoint — they layer two or three together. Well-optimized Shopify stores generate 8–15% of total revenue from upsell and cross-sell offers alone.
Not every app covers every touchpoint. Some are all-in-one. Others are specialists. Here's what each one actually does.
1. Selleasy — Best All-Around Upsell App
Rating: 4.9 ★ (2,174 reviews) · Pricing: Free plan available · Installs: 42,000+
Selleasy covers all four upsell touchpoints: product page frequently-bought-together widgets, cart drawer upsells, checkout add-ons, and post-purchase offers. The free plan includes every feature for stores doing up to 50 orders per month with no revenue share — which makes it the easiest starting point for smaller stores.
Merchants consistently praise the setup speed. Most reviews mention getting upsells live within 30 minutes. The app integrates cleanly with most Shopify themes without layout issues, and the support team is responsive if something doesn't look right.
Best for: Stores that want one app covering every upsell touchpoint without paying upfront.
2. ReConvert — Best for Post-Purchase Upsells
Rating: 4.9 ★ (5,093 reviews) · Pricing: Free plan available
ReConvert (now branded as Upsell.com) is the most reviewed upsell app on Shopify, and it earned that position by doing one thing extremely well: post-purchase funnels. After a customer completes payment, ReConvert shows one-click upsell offers on a customizable thank-you page. Some merchants report AOV increases of 20% from post-purchase offers alone.
The app also handles pre-purchase and in-cart upsells, but post-purchase is where it shines. The funnel builder is drag-and-drop, and you can create multi-step sequences where declining one offer triggers a different one. (For a deeper look at post-purchase strategy, see our post-purchase upsell setup guide.)
One thing to watch: a January 2026 review flagged that ReConvert shows ads on checkout pages as part of a network feature. Check your settings to make sure you're not showing third-party promotions on your checkout without realizing it.
Best for: Stores focused on maximizing revenue after the sale is already made.
3. Kaching Bundles — Best for Product Bundles and Volume Discounts
Rating: 5.0 ★ (3,932 reviews) · Pricing: Free to install
Kaching holds a perfect 5.0 rating across nearly 4,000 reviews — which is rare for any Shopify app at that scale. The app focuses on bundle offers: "Buy 2, Save 10%," BOGO deals, mix-and-match bundles, and quantity breaks that display directly on your product pages.
The bundle widgets are designed to blend with your theme, not look like a bolted-on popup. Merchants report that Kaching bundles don't slow down page load, which matters because every extra second of load time drops conversions by roughly 7%.
The developer also offers a separate Kaching Post Purchase Upsell app and a Kaching Cart Drawer app, so you can stack multiple touchpoints if needed — though that means managing multiple apps.
Best for: Stores that want to increase units per order through bundle pricing and volume discounts.
4. AOV.ai Bundles Upsell — Best Bundle Builder
Rating: 5.0 ★ (1,211 reviews) · Pricing: Free to install
AOV.ai focuses specifically on bundle creation: volume discounts, AI-powered frequently-bought-together suggestions, mix-and-match bundles, and fixed bundles. The bundle builder is visual and no-code — you pick products, set discount tiers, and publish.
What sets AOV.ai apart from Kaching is its AI recommendation layer. The app analyzes purchase patterns and suggests which products to bundle together based on actual order data, not your gut feeling. For stores with large catalogs where manually creating bundles isn't practical, this automation is the main draw.
Best for: Stores with 50+ products that want AI-generated bundle suggestions rather than manual setup.
5. BOLD AI Upsell & Cross-Sell — The Veteran Option
Rating: Mixed · Pricing: From $9.99/month (14-day free trial)
BOLD has been in the Shopify upsell space longer than most competitors. The app covers pre-purchase, checkout, and post-purchase upsells with AI-powered offer targeting. It creates frequently-bought-together bundles, order bumps, true upsells (upgrading to a better version of the product), and Buy X Get Y offers.
The AI matching is BOLD's strongest feature — it analyzes your store's order history to personalize which upsell each customer sees. For high-traffic stores with enough data to feed the algorithm, this can outperform manual offer selection.
The trade-off: BOLD charges $9.99/month for 200 upsell views, and scaling up costs more. Some merchants in recent reviews have flagged unexpected conversion drops after installation, likely from offer popups interrupting the checkout flow. Test carefully before going live store-wide.
Best for: Established stores with high traffic that want AI-powered personalization and can afford the learning curve.
6. Wiser AI — Best for Product Recommendations
Rating: 4.9 ★ · Pricing: Free plan available
Wiser takes a different approach than traditional upsell apps. Instead of showing popup offers, it places AI-driven product recommendation widgets across your store: frequently bought together, recently viewed, "shop the look" sections, and slide cart recommendations. The widgets feel more like native product discovery than a sales pitch, which can reduce the "pushy popup" fatigue that some customers experience.
Wiser has been around for five years and merchants describe it as a steady, reliable part of their stack. The AI improves over time as it collects more browsing and purchase data from your store.
One important caveat: Wiser uses a revenue share model on some plans. At least one merchant review flagged being charged a percentage of all site sales — not just sales attributed to Wiser's recommendations. Read the pricing terms carefully before installing.
Best for: Stores that want subtle, always-on product recommendations rather than popup-style upsell offers.
7. EasySell — Best for COD Stores With Built-In Upsells
Rating: 4.9 ★ (801 reviews) · Pricing: Free to install
Most upsell apps assume your customers go through Shopify's standard checkout. But if you're running a COD (cash on delivery) store — common in MENA, South Asia, Southeast Asia, and Latin America — the standard checkout isn't your primary flow. EasySell replaces the default buying flow with a conversion-optimized order form that has upsells built directly into it: pre-purchase offers, post-purchase upsells, quantity discounts, and one-click add-ons like shipping protection or gift wrapping.
The difference from standalone upsell apps is that EasySell's offers live inside the order form itself — customers see them as part of the buying process, not as a separate popup or page. For COD stores, this matters because the form is the checkout. The app also includes OTP verification, partial payments, and fraud prevention tools that COD merchants need anyway, so it replaces what would otherwise be three or four separate apps.
Best for: COD merchants who want upsells, fraud prevention, and order form optimization in a single app.
Which Upsell App Should You Pick?
The right app depends on where your biggest AOV opportunity sits:
- Just getting started with upsells? Start with Selleasy's free plan. It covers every touchpoint and you can upgrade later.
- Already converting well but want more from existing buyers? ReConvert's post-purchase funnels add revenue without touching your pre-purchase flow.
- Selling products that naturally bundle? Kaching or AOV.ai will increase units per order through volume discounts and mix-and-match offers.
- Running a COD store in emerging markets? EasySell gives you upsells inside the order form alongside fraud prevention — without stacking three separate apps.
- High-traffic store wanting AI personalization? BOLD or Wiser use purchase data to show the right offer to the right customer automatically.
Install one app, set up two or three offers, and measure for two weeks before adding complexity. The stores generating 8–15% of revenue from upsells didn't get there by installing every app on this list — they picked one, optimized it, and let the data tell them what to add next.
